UCSD Admissions Director Mae Brown said Tuesday that the message sent Monday was supposed to be sent to about 18,000 accepted students, not all 47,000 applicants. The invitation was for a day on campus.

She says she later sent a mass e-mail apologizing for the confusion.

Brown says the mailing was sent to rejected applicants because of a technical error. She says no one has been disciplined for the error.

Brown says the admission staff has been fielding calls from parents and distraught students who had received rejection letters in mid-March.
